As we advanced up the Camiño de Chasna, a road only by name, the _quintas_ were succeeded by brown-thatched huts, single or in clumps. On the left, 3,400 feet above sea-level, stood the Pino del Dornajito ('of the Little Trough'), one of the few survivors in this once wealthy pine-ground. The magnificent old tree, which was full grown in the days of the conquest, and which in the seventeenth century was a favourite halting-point, suffered severely from the waterspout of November 7, 1826; but still measured 130 feet long by 29 in girth. The vegetation now changed. We began brushing through the arbutus (_callicarpa_), the wild olive (_Olea excelsa_), the Canarian oak, the daphne, the myrtle entwined with indigenous ivy (_Hedera canariensis_); the cytisus, the bright green hypericum of three species, thyme, gallworts, and arborescent and other ferns in numbers, especially the hare's-foot and the peculiar _Asplenium canariense_, the _Trichomanes canariensis_, and the _Davallia canariensis_; the _brezo_ (_Erica aborea_ and _E. scoparia_), a heath whose small white bells scented the air; and the luxuriant blackberry, used to fortify the drystone walls. The dew-cloud now began to float upwards from the sea in scarf-shape, only a few hundred feet thick; it had hangings and fringes where it was caught by the rugged hill-flanks; and above us globular masses, white as cotton bales, rolled over one another. As in the drier regions of Africa the hardly risen sun made itself felt. At 10.20 A.M. we had passed out of the cultivated region to the Montijo, or Monte Verde, the laurel-region. The 'wood' is the remains of a fine forest accidentally fired by charcoal-burners; it is now a copse of arborescent heath-worts, ilex (_I. Perado_), and _Faya_ (_Myrica Faya_), called the 'Portugal laurel,' some growing ten feet high. We then entered upon rough ground, El Juradillo ('the Hollow'); this small edition of the Mal Pais, leading to the Canadas, is a mass of lava-beds and dry _barrancos_ (ravines) grooved and sheeted by rushing torrents. The latter show the anatomy of the land--tufas, lavas, conglomerates, trachytes, trachydolerites, and basalts of various kinds. Most of the rocks are highly magnetic, and are separated by thin layers of humus with carbonised plant-roots. Around El Juradillo rises a scatter of _montanetas_, shaped like half-buried eggs: originally parasitic cones, they evidently connect with the main vent. About 1 P.M., after four hours' ride, we dismounted at the Estancia de la Sierra (6,500 feet); it is a pumice-floor a few feet broad, dotted with bush and almost surrounded by rocks that keep off a wind now blowing cold and keen. Consequently, as broken pots and bottles show, it is a favourite resting-place.
